Fill DataGridView from SQLite DB (C#)

Question

I\'m trying to fill a datagridview from an SQLite database.

I\'ve found plenty of ways of doing this. However, I have pre-existing columns in my dgv (Item, Quantity)

If you dont want to disturb the columns you can read the rows one by one using SQLiteDataReader and put it into the datagridview..

private void button1_Click_1(object sender, EventArgs e)
{
    conn.Open();
    SQLiteCommand comm = new SQLiteCommand("Select * From Patients", conn);
    using (SQLiteDataReader read = comm.ExecuteReader())
    {
        while (read.Read())
        {
            dataGridView1.Rows.Add(new object[] { 
            read.GetValue(0),  // U can use column index
            read.GetValue(read.GetOrdinal("PatientName")),  // Or column name like this
            read.GetValue(read.GetOrdinal("PatientAge")),
            read.GetValue(read.GetOrdinal("PhoneNumber")) 
            });
        }
    }

}
